Application filed November 21, 1907. Serial No. 493,146.

To all whom it may concern:

Be it known that I, CHARLES GEORGES, a citizen of the Republic of France, residing at St. Cloud, France, have invented new and useful Improvements in .or Relating to Embroider'yfMachines, Vof which the following is a specification.

yThis invention relates to improvements in embroidering machines of that class wherein automatic Vmovement .of the fabric or embroidering frame is obtained by means of a jacquard transmission mechanism.

`The in-velition includes a plurality of droppers, `controlled by the acquard, and one of the novel features of .the invention is the provision of longitudinally movable members for controlling and .effecting movement of the embroidery frame and wherein said longitudinal members are in turn controlled by plie droppers operated by the jacquard care s.

A further novel feature of the invention consists in an improved form of droppers having various sizes whereby they may be combined and recombined to .obtain an indefinite number of positions of the embroidering frame.

4Other features of the invention will be more fully described in connection with the accompanying drawings and will be more particularly pointed out and ascertained in and by the appended claims.

A complete -side elevation of a machine embodying my invention is shown in Figures 1 and lil.

Fig. 2 is a sectional view on lines C, D, E, 1F of Fig. 1. Fig. 2A is a sectional view on line 2A--2A of Fig. 1. :F ig. Bis a vertical sectional view on line GH .of Fig. .1,

Like characters of reference designate similar parts throughout the different figures of the drawings. v

The frame of the machine is ldesignated at 8 and the embroidery frame at 31. The frame 3 1 is supported on the main frame 8 by VI neans of acounterrbalance mechanism which may V,consist of the .following con-Y structionzQYokes comprising horizontal track members 36 andvertieal members 87, are provided on each` end of `the frame 31, and "the track Vmembers .36 engage land are supported on the periphery of wheels 35. Said-wheels 35 are supported on the endsof counter-'balance levers 32, pivotally ymounted to the-frame at 33, and connected at their -inE ner ends by counter-balance weight The counter-b al ance mechanism permits ofmo-viment of the frame -3-1 in angT vdesired .direction in the plane in which it lies.

1 designates a jacquard roller for thecards which is mounted yon a bracket 41, .piotedart 42, Vand provided with an anti-friction roller 43 adapted to be operated by `cam .4. The shaft .6 is rotatably mounted in a .bearing f7. A rod 15 is rigidly supported on the frame .at 16 and .carries a dropper frame 2 which slotted at 2a to receive the shaft 44, so that when the shaft 44 is raised it `will raise fthe roller 1 and the roller 1 will .be movable lon.- gitudinally on the shaft .141 Vwith the frame 2. The frame 2 is provided with guides t6 in which droppers 3 are longitudinally movable and in which said droppers are disposed in .a manner `to .be actuated 'by the .cards `on the roller 1. In .the usual.construe tion the .card is perforated and when the roller 1 -iS raised those droppers which do not register with the perforations in the card will be raised while those droppers which register with .the plrforations in the card will not `be raised. 'l with heads 45 of different sizes, the purpose of which novel construction will hereinafter more fully appear. Movement .of the frame 2 to the left is effected by a earn 5, mounted on shaft V6, andthe frame `2 is retained in en.- gagement with the .cam 5 and is restored -to the right by spring .9 mounted .on shaft '15 and interposed between the frame 2 and fa guiding support 13. As shown .in Fig. y2, two rows of Stoppers 3 are provided vand the frame 2 is provided with stops l@ adapted for engagement with .those Stoppers which have been raised by the jacquard card. 0n the upper .end of the `Shaft 6, .a cam '23 is mounted, the purpose of .which will hereinafter more fully appear.

The frame 8 is provided with'guiding supports V1d, which serve with the .guiding sup.- ports 13, .to support a plurality .of Ilongitudinally .movable ars. 'lhe bars are-indicated at 12 and in the construction showntwo 'bats are used. Each bar 12 is provided with ,a stop 11 `between whichiand .-thelstops 1t) -the selected and -elevateddro pers are .disposed for the purpose of controing movement of the ybars l12.

A locking device is provided vfor automatical-ly locking the bars V12 in `vwhatever `position lthey .may Ahave 'been displaced and e upper ends ofthe droppers are provided holding said bars in a looked position for aV redetermined time and subsequently reeasing them. Preferably the improved locking device acts frictionally in the performance'of its function.

As shown a bracket 47 is mounted on parts 15 and 14V and sup orts at its upper end a pivotally connectedp arm 49 provided with a roller 22 adapted to be actuated by the cam 23. The arm 49 is adapted to be raised by the cam 23 and lowered by springs 21, secured to said arm and the bracket 47. The arm 49 carries a locking member 20 which referably terminates in a wedge-shaped fork, as clearly shown in Fig. 2. The coperating member of the locking device comprises an intermediate wedge-shaped memer 19 and outer retaining members 18, between which the bars extend and which niembers may conveniently be adjustably 1nount ed on the bracket 47 by means of a rod 50 as clearly shown in Fig. 2. It will be obvious that as the member 20 is depressed it will en` gage the arms 12 and force the same frictionally into engagement with the retainers, which latter serve effectively to prevent spreading of the bars 12. Springs 17, connected with the bars 12 and the frame 8, serve to normally shift the bars 12 to the right when the same are released by the locking device.

The bars 12 are provided with means by which they are connected with the frame 31 and as shown said means consists of levers 24 and 25, pivotally mounted to the bars at 38 and 39 respectively, and provided with slots 26 and 27. Said levers are provided with sector-shaped extensions having slots 40 adapted to be guided by screws 42 and 43 disposed on the bars 12. The frame 31 is provided with yoke 29 having a pin 28 which extends through the slots 26 and 27, of said levrs 24 and 25, and bearing members or bushings having diametrically opposite flattened sides are rotatably mounted on said pin 28 to provide suitable bearings for the slots 26 and 27. Said bearing members or bushings are clearly shown in Fig. 3 and are designated at 51.

The yoke 29 is adjustably mounted on a bracket 52, by means of nuts 30 and said bracket 52 is secured to the frame 31.

The operation is as followsze-When the card cylinder 1 is lifted it will raise one or more droppers 3, which do not register with the openings in the card, to bring the heads 45 between the stops 10 and 11. W'hen the frame 2 is shifted to the left, the raised heads 45 will be engaged between the stops 10 and 11 and if a considerable number of droppers 3 have been raised the bars 12 will be shifted a considerable distance to the left whereas if a relatively few droppers 3 have been raised the bars 12 will be shifted to the left a cormovement imparted to the frame 2 is always the. same but it will be readily understood that the different formation or shape of the heads 45avill render it possible to combine and recombine said heads 45 in such a manner as to shift the bars to the left to an distance or amount which may be varied a ost indefinitely. If the droppers of onerow onlyare raised only one of the bars will be shifted and if a less number of one row of droppers is raised than is raised in the other row the corresponding bars 12 will be shifted a greater' distance than its companion bar. If only the droppers of the first row have been raised only one of the bars will be shifted and the other bar will remain in a position of rest. The cam 23 is so timed with respect to the cams 4 and 5 that it will immediately release the arm 49 so that the wedge-lock 20 will be drawn into locking relation with the bars 12 as soon as they have been shifted to the desired point and said spring will hold the wedge-member 20 in locking relation with the bars 12 to retain the same in their shifted position. The cam 23 is so timed with respect to the cams 4 and 5 that it will permit the cams 4 and 5 to return to a starting position before the cam 23 raises the wedge-lock 2O to free the bars 12 and permit them to be shifted to the right by the spring 17. In the interval in which the bars 12 are locked the embroidering needle enters the fabric and completes a stitch. As soon as the stitch is completed and the cams 4 and 5 have been returned to a starting position, the cam 23 will raise the arm 49 and free the bars 12 and the spring 9 in the meantime will have returned the frame 2 to a starting position.

the left will carry the pin 28 to the left in a horizontal line of movement providing the displacement of the bars 12 and 12 Vis equal. Such lateral movement of the pin 28 will cause a corresponding shifting movement of the frame 31 to the left. If the bar 12A is displaced to the left, thereby carrying the member 25 with it, the pin 28 will be moved ob liquely upwardly to the left a distance corresponding to the movement imparted to the i bar 12. 1f the bar 12 is displaced, leaving the bar 12 in a position of rest, the member 26 will cause an oblique downward displacecorresponding movement of the embroider-Y ing frame 31. If both of the bars 12 and 12 have been displaced an unequal distance from right to left the pin 28 will be moved obliquely upwardly or downwardly depending upon which of the bars has been shifted a greater distance. It will thus be seen that an almost indefinite number or variety of movement can be imparted to the frame 31 through the members 25 and 26 and it will also be obvious that by reason of the novel The displacement of both bars 12 and 12 toV ment of the pin 28 from right to left and a iro respondingly less distance. The shifting l construction of the dropper head 45 an al- 1.3.0

most infinite numb er of combinations thereof can be effected to obtain any desired displacement of the bars 12 and 12.
